Bearingless encoder for shaft diameter up to 30 mm.

The RLI20 bearingless encoder, consisting of magnetic ring and sensor head, with its installation depth of only 16 mm is ideally suited for narrow installation possibilities. Its contactless measuring principle enables error-free operation even under adverse environmental conditions and a long service life. IP68 / IP69k protection, special encapsulation technology, and tested resistance to cyclic humidity and heat provide maximum reliability even in unprotected outdoor use. This bearingless encoder can be mounted on shafts up to max. 30 mm diameter.
